TIL about Reverse Polish notation, which is a different style of writing math equations. 3+4 is instead written as 3 4 +. One pro is that it removes the need for the Order of Operations. (en.wikipedia.org)

Generally, with RPN you work from the inside out letting the results from operations inside the brackets sit on the stack until you need them. So the need for Order of Operations isn't removed, but you don't need special keys on the calculator for it. You do have to keep track of what's where on the stack, but this becomes second nature after a while.
